COMPONENTS OF TEST CIRCUIT FOR MEASURING
ELECTRICAL CHARACTERISTICS
TEST CIRCUIT
INDUCTOR FOR THE OUTPUT PIN
an inductor between the V
voltage drop to output enable high level. In terms of AC, the inductor makes output-port impedance higher to get
enough gain. In this case, large inductance and Q is suitable (Refer to the following page).
CAPACITORS FOR THE V
the input and output pins.
can be supplied against V
impedance. Their capacitances are therefore selected as lower impedance against a 50 Ω load. The capacitors thus
perform as high pass filters, suppressing low frequencies to DC.
10 MHz operation, increase the value of coupling capacitor such as 10 000 pF. Because the coupling capacitors are
determined by equation, C = 1/(2 πRfc).
